Actually, it's psychologically damaged individuals that say mean things when they hear things they don't like; it's a coping mechanism originating from the Amygdala due to the individual's lack of connections in the frontal lobe rendering them incapable of processing the information any way other than a primitive fight-or-flight response. This is seen among leftist liberals all the time when the all-powerful government that they submit to is questioned, but is also very apparent among right-wing statists that suffered abuse from authority figures in their early childhood.
In a way though, I'm flattered - obviously you care about my thoughts and opinions, otherwise you wouldn't feel so threatened by them as to lash out with "mean things." I, on the other hand, couldn't possibly care less what you have to say, hence why I don't respond with nasty remarks and ad hominem attacks.
